This application is a division of my conding a plication,Serial Number183,392, ied Aprii) 13, 1927, to which reference may be had for a morecomplete description of the cash register to which the present inyentionhas been applied. While thek im- .provementssetforth in this applicationare shown in conjunction with a particular type of cash register asillustrated in the parent application their utility is by `no meanslimted to'this specific embodiment. The improvements are of such anature that they may be applied in various modifications to many othertypes of cash registers and accounting machmes.

This invention has for its principal object the provision of improvedmeans for preventing' the simultaneous operation of more than one key ofa group; which means shall be simple in construction, elicient inoperation, and capable of expeditious andfinexpensive manufactureand'assembly.

More'specifcally, it is an object of my 1nlvention to provide key stopsor pendants so constructed as tobe fulcrumed without the necessity ofproviding the usual pivot studs.

Another object is the provision of a construction whereby said key stopsor endants may be speedily assembled and attac ed to o r detached fromthe machine as a unit. With these and incidental objects inview theinvention consists of certain novel ifeayform of embodiment of which ishereinafter j 32 (Flgs'. 1 and 2) which are divided into .i .kreis tureslof construction and combination vof arts, the essential elements ofwhich arey set orth inthe appended claims anda preferred described kwithreference to the drawings which accompany and form part of thisspecifcation. Y

0f said drawings: y y Fig. lis a vertical sectional view of a cashregister in connection with which the 'present invention is illustrated.'j L Fig. 2 is a` rear view of the machine showing the arrangement ofthe groups of keys and the series of key stops associated therewith,part of the structure being broken away adjacent the upper portion ofcertain of the stops. g.'3 is 'a side elevation showing the rear portionof a key in conjunction with aL key stop member.

Framework The various parts of the mechanism of the lllustratlve machineare supported by a suitable framework comprising two parallelsidethrough the side plates and into the cross members. The framework justdescribed rests upon av drawer base 26 and may be attached thereto byscrews passing'through the cross members 22 and V23 and into the top ofthe drawergbase. `As best shown in Fig. '1, the mechanism is enclosed bya cabinet 27 'which may be made of any desired material and rests uponthe drawer base. The cabinet is slotted at 28 to receive and guide thekey levers in their movements and is, furthermore, apertured at itsupper end to permit the viewing of vthe `elevated throughy suitablediaphanous material at the front and rear.

i Keg/s,k key coupler and full stro/ce device The illustrative machinecomprises keys groups; one group for each denominational order, such as,for example, units, dimes and dollars.v Obviously, more amount keyscould vbe provided if more groups or higher denominational orders weredesired, so as to increase the capacityof the machine. A special key y31(Fig. 2) is alsoprovided and is designated yas they No sale key. Thiskey forms no part of the present invention as no controlling key stop isassociated therewith, and therefore no further mention thereof is deemednecessa y y .y f As-'shownin B ig. 1, the amountkeys 32 are indicators vifi pivoted upon a shaft 63, which shaft is suitably supported by theside plates 2O and 2l. Said keys 32, which carry at their respectiveoutward ends or front portions thereotl suitable key cups bearing;indicia designating the ilature ot the keys, play in the vertical slots2S which are formed in the cabinet At their rear ends the keys areguided by slots formed in a plate 36 secured to the cross bar b v screws3T.

Eztending between the side 2l and restingupon the rear ends ot the keysis a key coupler 39. The key coupler is pivotally supported by means ofplates (Fig. l) attached to the key coupler and suitably apertured toreceive a transverse shalt 42, which is located approximately above theaforementioned shal't 33 and is supported by the side plates 2O and 21.It will be obvious that when the forward ends ot the keys are depressedthe key coupler 39 will be rocked clockwise so that its rearward endwill enter the notches 3S of the depressed keys. The purpose of such keycoupler mechanism is well known in the art and need not be discussedherein.

plates 2O and Key stops lVhile the concentric edges l5 et theupstandingportions t6 (Fig. l) of the various keys in conjunction withthe key coupler are intended to lock all unoperated keys after theinitial movement of the key coupler, it is desirable to providemechanism to prevent depression oi more than one key in a bank during" asingle operation of the machine. .For this purpose I provide a seriesozt key stops G2. the wedge-shaped lower ends of which coopeate with therear ends of the keys 32 in the usual manner so that upon the depressionoi' a key in a bank the end of the operated key will lill the onlyavailable gap between the key stops in that group and thus lock theremaining keys. I have so constructed said stops that they may besuspended without the necessity of providing the customary pivot studs,and at the same time ellectively portorm their intended functions: torthis purpose I form the upper end ot each ot said stops with a reducedportion terminatine` in a head Gfr. As best shown in Fig. 2. the guideplate 36, heretofore mentioned, bent so as to form the double channelsections G5 and G6. The lower channel section G5 is provided with aseries ot rectangular slots 67 which are somewhat wider than the widthoit the reduced portions 63 of the key stops. The key stops applied tothe plate 3G in such a manner that the reduced portions tit within therectangular slots 617. the head 6l ot' each of the key stopsrestinefupon a ledge (S51 formed by the chan- After the key stopsnelling ot the plate 36. are in place the plate 36 is attached to the-cross bar 25 by any suitable means, such as screws 37. It will thus beseen that said stops may be readily and expeditiously placed in positionou the plate 36 and the resultingl assembly consisting,` ot said stopsand plate attached to the machine as a unit and that likewise said stopsand plate may il desired be detached as a unit :trom the machine bysimply removing the attachingr screws 3T. The diilercnee between thewidth ot each slot GT and the reduced portion (53 of the associated keystop (32- permits a slight oscillatory movement ot the key stop so thatthe key stops. function in exactly thev same manner as it' they wereulcrumed by means ot a pin. It may be noted that either side ot head(ist may serve as a ulcrum Vtor its stop member 62, thus providing' torpivotal movement ot said stop in either direction from normal position.

lrvhile the 'torni ot mechanism herein shown and described is admirablyadapted to it'ullill the objects primarily stated it is to be understoodthat this embodiment is merely illustrative. since the invention issusceptible of embodiinent in various other Jorms all comingwithin thescope ot the claims which follow.
